In the drawing the numeral 1 designates in a general way a part of any suitable sharpening device having an overhanging arm 2 from which the blade holder is suit ably :supported'so that the blade will be positioned betweenv honing or stropping rolls 3.

Theblade-holder is formed from a blank which is cut or stamped and shaped so as to form two spring prongs or arms 3 adapted to be clamped to the overhanging arm of the. machine so that the two arms will hold or press the blade with spring pressure against the honing or stropping roll that will be brought against the blade.

'From the lower connecting neck of these prongs or arms depends a jaw 4, while the portion of the metal from between the prongs is bent outwardly and then inwardly to form a loop member 5 and then bent downwardly toform a second jaw 6.

To the accomplishment of the'foregoing 5 and-such other-"objectsyas may hereinafter appear the invention-consists in the fea tures hereinafter particularly described and then "sought'to' be clearly defined by the claims, reference being had to the accome 40 panying drawing-"forming a part hereof, and

Figure 2 is a perspective View of the blade-holder Figure 3 is a bottom-plan view of the holder; Figure a is a front view of the holder showing a safety-blade positioned therein, and with a portion of the spring arms broken away;

Figure 5 is a horizontal section, on an enlarged scale, through the lower portion of One of the jaws, for instance jaw 4, is slitted at opposite ends and the slitted. portions bent-inwardly to form centering prongs :or lips T-designed to-enter openings usually formed in some types-of safety blades so as to'serve in positioning the blade properly between the clamping jaws as illus trated in Figure 43. One jaw is also formed with inwardly bent lips 8 which serves as a bearing for the upper. edge of a safety blade having only one cutting edge, and they also serve to prevent side movement of one jaw beyond the edges of the other jaw beyond which they may project as -:illustrated in Figures 1 and 2. Both jaws are formed at their lower edgeswith trans- 'versely extending grooves 9 and to one side of each groove are outwardly extending bosses or studs 10, the jaw 4 being formed with two of the studs and the jaw 6 with one positioned substantially centrally or midway between the two studs of the other jaw, and each stud is formed with a transverse groove 11. The grooves 9 and 11 are designed to form seats for the opposite sides of the back of an old style razor blade and prevent it from slipping when gripped by the jaws; and the end grooves in jaw 4- also serve to facilitate or direct the proper seating of such razor-blade between the jaws. The bosses or studs on the gripping faces of the jaws constitute or afford three points of contact with the blade gripped by the jaws which insures a better grip on the blade, and if the blade, as an old style razor, has a rounding or curved back the tendency of the blade to slip or change its position is guarded against. The jaws are drawn together to clamp the blade in place by a threaded bolt 12 and thumb nut 13 between which nut and one of the jaws is a thimble or sleeve 14. The beaded end of the bolt is formed with an angular shoulder 15 which fits in an elongated slot 16 in the jaw and prevents the bolt from turning when the thumb nut is screwed up; and this elongated slot permits a limited vertical adjustment of that jaw when desirable. This is sometimes necessary as old style razors do not always have the back project to the same extent beyond both sides of the razor blade. When such is the case the blade would stand obliquely to one side or the other of a vertical line, ac cording as the excess projection may be to one side or the other, and under such circumstances the blade would not stand in proper position for honing or stropping. To bring the blade into proper position an adjusting screw 17 is passed through the lower member of loop 5 and threaded into the upper member so that by expanding or contracting the loop as necessary the jaw will be lowered or raised to the extent necessary to tilt and bring the blade from an oblique position to a proper vertical position for honing or stropping. In Figure 1 the dotted lines indicate the position of the jaw and loop when the blade is in one oblique position and'the full lines indicate the expansion of the loop to tilt the blade into the vertical position indicated by full lines. If the blade when placed between the jaws should stand obliquely in the other direction from that indicated in Figure 1, then the loop would be contracted to bring the blade into vertical position for honing or stropping.

I have illustrated and described the preferred details of construction in the form of blade-holder illustrated but changes can with a plurality of gripping contact points for a blade and disposed to have the contact point of one jaw to lie to one side of a contact point of the opposite jaw.

3. A blade-holder for sharpening devices, said holder comprising oppositely disposed gripping jaws each formed with transversely extending grooves at the free ends of the jaws, and inwardly projecting studs formed with transversely extending grooves.

t. A blade holder for sharpening'devices, said holder comprising oppositely disposed gripping jaws with a loop formed at the upper portion of one jaw, and means for contracting and permitting expansion of said loop for vertical adjustment of its attached jaw.

5. A blade holder for sharpening devices, said holder comprising oppositely disposed gripping jaws, one jaw being an extension of spaced parallel spring supporting arms and the other being a continuation of a portion removed from between said arms shaped into a loop and extended to form the second jaw, means for contracting and permitting expansion of said loop to effectvertical adjustment of the attached jaw, and means for contracting one jaw towards the other.

In testimony whereof I aflix my signature in presence of two witnesses.
